Arguments

.tbl

A tbl object.

.funs

List of function calls generated by funs(), or a
character vector of function names, or simply a function.

Bare formulas are passed to rlang::as_function() to create
purrr-style lambda functions. Note that these lambda prevent
hybrid evaluation from happening and it is thus more efficient to
supply functions like mean() directly rather than in a
lambda-formula.

...

Additional arguments for the function calls in
.funs. These are evaluated only once, with tidy
dots support.

.predicate

A predicate function to be applied to the columns
or a logical vector. The variables for which .predicate is or
returns TRUE are selected. This argument is passed to
rlang::as_function() and thus supports quosure-style lambda
functions and strings representing function names.

.vars

A list of columns generated by vars(),
a character vector of column names, a numeric vector of column
positions, or NULL.

.cols

This argument has been renamed to .vars to fit
dplyr's terminology and is deprecated.

Value

A data frame. By default, the newly created columns have the shortest
names needed to uniquely identify the output. To force inclusion of a name,
even when not needed, name the input (see examples for details).
